Subject: s390/char : Rename EBCDIC keymap variables
Git-commit: aa0f2dd4de202c185b1156b1d43eb23e457e9a3c
Patch-mainline: v4.17-rc1
References: FATE#327159, LTC#174716, bsc#1121996
The Linux Virtual Terminal (VT) layer provides a default keymap
which is compiled when VT layer is enabled. But at the same time
we are also compiling the EBCDIC keymap and this causes the linker
to complain.
So let's rename the EBCDIC keymap variables to prevent linker
conflict.
